IMPROVEMENT IN GRAIN AND CLOVER THRASHERS.

Specification forming part of Letters Patent No. 156,641, dated November10,1874; application filed July 6, 1874.

To all whom it may concern:

Be it known that we, DAVID LIPPY, of Mansfield, Ohio, and ZALMON S.STOCKING, of Cleveland, Ohio, have invented a new and useful Improvementin Machine for Thrashing Grain and Hulling and Cleaning Glover, of whichthe following is a specification:

The invention relates to an improvement in machines for thrashing grainand hulling and cleaning clover; and consists in the novel constructionand arrangements of mechanism hereinafter described, by which thecloverseed is removed from the clover-heads and effectually cleaned andseparated, the de vices being so arranged that by throwing off the beltwhich aetuates those designed for treating the clover the machine may beemployed for thrashing grain. The object of the invention is to providean efficient means of hulling, separating, and cleaning clover-seed andits analogues, and also to provide a machine for thrashing grain, thetwo being associated in a single machine which is capable, with a slightchange, of use for either purpose.

In the accompanying drawings, Figure 1 is a plan or top view of amachine with our improvements. Fig. 2 is a longitudinal vertical sectionof the same, the elevator a; removed. Fig. 3 is a side elevation withthe elevator 00 attached, the latter in section. Fig. 4. is a detachedview of the clover-beater and appurtenances. Fig. 5 is a detached viewof the devices for vibrating the shoe R.

The machine consists of a frame, X, to which a feed-table, g, issecured, and from which the clover is moved by the feed-roller G to theendless apron H, by which it is carried under the bcaters-O and A, bothof ordinary construction. From the upper end of the apron H thecloverstalks pass over upon. the endloss apron L, which operates as astraw-carrier, and conveys the stalks over the end of the frame. A steelcutter, v, is placed in an inclined position adjacent the separator A,and another in proper proximity to the beater O, by which the stalks orstraw that may wrap about and clog the devices are severed and reducedto a condition to be transported with facility. At the point where theclover passes from the apron H to the apron L the heads of the cloverare separated from the stalks by the beater B, which is of oval form,and has a rapid rotary movement in the same direction as the endlessapron. The heads of clover thus separated descend through the space 12upon the inclined bottom board T, from which they pass onto theconductor M, hinged to the board T, and leading to the clover-hullingcylinder P. From the conductor M the cloverheads are dropped upon thedeflecting-bar E, which is covered with a strip of leather, 6, serratedin such a manner that the teeth 19 on the hulling-cylinder 1? may passbetween the teeth 6 of the leather strip, thereby preventing the descentof the clover-heads below the leather, so that they pass over thehulling-cylinder P, which is nearly inclosed in a concave, consisting ofthe heads 0 and staves Q, the heads being properly attached to securethe stavcs in place. The huller P consists of a toothed cylinder, whichrests in bearings on the removable slides p, the teeth 12 of thecylinder passing between the teeth t on one of the stavcs Q. Thus thecylinder and its appurtenances may be removed from or inserted into theframe X at pleasure by simply slipping the belt that actuates it andremoving one of the slides p. After passing through the huller theclover-heads pass out through the exit 0, through which they are blownby the operation of the fan N, over and upon the upper sieve F, throughwhich the seed drops onto the lower sieve F; thence upon the inclinedshoe R, descending thereon to the seed-box S, the shoe B being vibratedlaterally by an cecentric connection with one of the revolving shafts(see Fig. 5) to speed the descent of .the seed. A valve, K, at the mouthof the fanchamber Z, serves to regulate the blast from the fan. Thetailings of the clover-heads pass over the end of the upper sieve F intothe chute Z, and are kept in motion by the movement of the shoe B, whichcauses them to descend upon the endless apron z of the elevator a, bywhich they are carried upward and discharged into the inclined spout J,whence they descend through the chute J to the feed-table Q. Theaccumulation of stray chaff inthe lower part of the apron z is preventedby the operation of the brush D, the edge of which lightly impinges uponthe apron, and also serves to prevent the tailings falling back.

I The larger portion of the tailings leave the elevator 00 near theboard M, and drop into a gutter, E, having in it a revolving screw, E,with a very wide thread, which conducts the tailings onto the bar E tobe rethrashed. The light chaff is blown from the machine off of theupper sieve F.

When it is desired to operate the device as a grain-thrasher the beltwhich actuates the cylinder P is thrown off and the boards M elevated tooccupya vertical position, the effect of which is to permit the grain tofall directly from the board T upon the upper sieve F, and thenceproceed onward, as the clover-seed does after it has reached the saidsieve.

The boards M may, as in the present in stance, be hinged to the board T,so as to be folded or extended, as desired, and the spout J may beshaken by an eccentric attachment with any suitable shaft.

The machine is driven by means of belts,

the power being communicated preferably at the shaft of the beater 0.

What we claim as our invention, and desire to secure by Letters Patent,is

1. The combination of the endless apron H, beaters O and A, and cuttersv, substantially as shown and described.

2. The combination of the endless elevatorapron z with the brush D,substantially as set forth.

3. The fixed inclined cutters v, for the purpose of stripping therevolving beaters A and O, substantially as set forth.

In testimony that we claim the foregoing improvement inthrashing-machines, as above described, we have hereunto set our handsand seals this 30th day of June, 1874.
